WOMEN'S PREMIER LEAGUE
Bristol Academy 1-2 Chelsea
With the top-of-the-table clash between Arsenal and Everton postponed, Chelsea took full advantage to move within seven points of the Toffees.
Jessica Smith's 57th minute header put the Blues in front, and though Michelle Green equalised 14 minutes later, Sanderson hit the winner from 20 yards within 60 seconds.
Blackburn Rovers 1-2 Doncaster Rovers Belles
Striker Katie Anderton gave the home side a 33rd minute lead with her ninth goal in as many games, and her 18th of the season.
But Donny staged a second half fight-back and after Naomi Chadwick's 77th minute equaliser, captain Vicky Exley grabbed the winner from a stoppage-time penalty.
Leeds Carnegie 1-2 Birmingham City
The visitors took a 10th minute lead through Jo Potter but then had to defend for long spells, particularly in the second half.
Substitute Ellen White seemed to have earned Leeds a point with an 84th minute leveller, but four minutes from time Gauntlett pounced to grab the winner.
Watford 0-3 Liverpool
Watford's unhappy afternoon started after just three minutes, when Maddy Hills put the relegation-threatened Reds in front.
Alyson Hastie doubled the lead in the 42nd minute, then 12 minutes after the break Hourihan saw red for handling the ball outside her penalty area.
That was just about the end of Watford's hopes, but to make sure Kelly Jones wrapped up victory for the visitors with the final goal three minutes from time.
Liverpool's win lifted them four points clear of the drop zone, but second-from-bottom Nottingham Forest now have three games in hand.
